\frac{d}{d x} (\frac{x ^{2} - 4}{x + 0.5})

\frac{x ^{2} + x + 4}{( x + 0.5 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{x ^{2} - 4}{x + 0.5})

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{\frac{d}{d x} ( x ^{2} - 4 ) ( x + 0.5 ) - \frac{d}{d x} ( x + 0.5 ) ( x ^{2} - 4 )}{( x + 0.5 ) ^{2}}

\frac{d}{d x} (x^{2} - 4) = 2 x

\frac{d}{d x} (x + 0.5) = 1

= \frac{2 x ( x + 0.5 ) - 1 \cdot ( x ^{2} - 4 )}{( x + 0.5 ) ^{2}}

Simplify

\frac{2 x ( x + 0.5 ) - 1 \cdot ( x ^{2} - 4 )}{( x + 0.5 ) ^{2}} : \frac{x ^{2} + x + 4}{( x + 0.5 ) ^{2}}

= \frac{x ^{2} + x + 4}{( x + 0.5 ) ^{2}}
